1 MPE EVALUATION OF MOBILE DEVICES Human exposure to RF emissions from mobile devices (47 CFR §2.1091) may be evaluated based on the MPE limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate, since exposures are assumed to occur at distances of 22 cm or more from persons. 1.1 LIMITS FOR GENERAL POPULATION/UNCONTROLLED EXPOSURE 2 Frequency Range (MHz) Power Density (mW /cm ) Averaging Time (minutes) 300~1500 F/1500 30 1500~100000 1.0 30 1.2 MPE EVALUATION FORMULA Pt Pd = 4 * Pi * R 2 Where 2 Pd= Power density in mW/cm Pt= EIRP in mW Pi= 3.1416 R= Measurement distance Report No.: FA572901 Page : 4 of 6 Report Version: Rev. 01

1.3 MPE EVALUATION RESULTS MPE Evaluation of Single Transmission Non-beamforming mode Maximum Frequency Antenna Gain Distance Power Density 2 Conducted 2 Limit (mW/cm ) Range (MHz) (dBi) (cm) (mW/cm ) Power (dBm) 2412~2462 29.10 3.86 22 0.325 1 5180~5240 25.73 4.3 22 0.166 1 5745~5825 21.47 4.3 22 0.062 1 Beamforming mode Maximum Frequency Antenna Gain Distance Power Density 2 Conducted 2 Limit (mW/cm ) Range (MHz) (dBi) (cm) (mW/cm ) Power (dBm) 2412~2462 27.49 8.38 22 0.635 1 5180~5240 24.77 8.45 22 0.345 1 5745~5825 20.78 8.50 22 0.139 1 Note: 1. For 2412~2462 MHz band 3.29/20 3.86/20 3.66/20 2 Directional gain = 10 * log((10 +10 +10 ) /3) = 8.38 dBi For 5150~5250 MHz band 4.3/20 3.2/20 3.5/20 2 Directional gain = 10 * log((10 +10 +10 ) /3) = 8.45 dBi For 5745~5850 MHz band 4/20 2.8/20 4.3/20 2 Directional gain = 10 * log((10 +10 +10 ) /3) = 8.50 dBi MPE Evaluation of Simultaneous Transmission 2.4 and 5GHz can transmit at the same time, MPE evaluation is as below formula PD1 / Limit1 + PD2 / Limit 2 + ….. < 1, PD = Power density Non-beamforming mode MPE Evaluation = Maximum MPE of 2.4GHz + Maximum MPE of 5 GHz = 0.328 / 1 + 0.166 / 1 = 0.491 < 1 Beamforming mode MPE Evaluation = Maximum MPE of 2.4GHz + Maximum MPE of 5 GHz = 0.635 / 1 + 0.345 / 1 = 0.980 < 1 Conclusion MPE evaluations of single and simultaneous transmission meet the requirement of standard.
